| Abstract(in English) | μ ITRON4.0-specification, established in 1999, includes the definition of mutex function, added for the hard real-time systems. Mutex supports priority inherita nce protocols and priority ceiling protocols, approach to solve the problem of (uncontrolled) priority inversion accompanying mutual exclusion. μ ITRON4.0-specification defines two versions of priority control rule strict rule and simplified rule. In this paper, we implemented the mutex function followed in both priority control rules on μ ITRON4.0-specification kernel and evaluated the differences of performance. As the result, in the case that task locks multiple mutexes, the simplified priority control rule enables to suppress the overhead of mutex operation. |
